What are the patterns in changing a fraction into a percent? I need this answer as soon as possible thankyou!
Answer:
See below.
Step-by-step explanation:
To change a fraction into a percent, divide the numerator by the denominator and multiply by 100%.
For example:
Example 1)
Change 1/2 into a percent.
1/2 = 0.5
0.5 * 100% = 50%
1/2 = 50%
Example 2)
Change 13/16 into a percent.
13/16 = 0.8125
0.8125 * 100% = 81.25%
13/16 = 81.25%

A. The system has exactly one solution.
B. The system has infinitely many solutions.
C. The system has no solution.
Answer:
I think it is A
Step-by-step explanation:
because there is only 1 slope which is 3 and the y intercept is 4
4x-y=3 how can I solve this
Help with this please
Answer:
slope=20
Step-by-step explanation:
rise= 100
run= 5
rise over run = 100/5
100÷5=20
so slope =20

Why in these types of questions(the image) I need to multiply the dominator by itself and by the nominator. and why I can't just multiply it just by itself.
Answer:
[tex]\frac{\sqrt{5x^{2} } }{\sqrt{3x^{3} } } =\sqrt{\frac{5}{3x} }[/tex]
Step-by-step explanation:
Simply because
[tex]A=\frac{5}{3} = \frac{5}{3}*\frac{3}{3} = \frac{15}{9} =\frac{5}{3}[/tex]
So its value remains Constant , It's simply as if you're multiplying by 1 which doesn't change anything at all
but when doing this
[tex]A=\frac{5}{3} = \frac{5}{3}*\frac{5}{3} = \frac{25}{9} \neq \frac{5}{3}\\[/tex]
You changed its value
[tex]A[/tex] now became [tex]A^{2}[/tex]
Hope you understand it

What is the slope of a line perpendicular to the line whose equation is: -3x -5y = 10 ?
Answer:
y= 5/3x - 2
Step-by-step explanation:
add 3x (-5y = 3x+10)
divide by -5y (y = 3/5x - 2)
flip the 3/5x (y=5/3x - 2)

What is
-4.5*(-2)=
(10points)
Answer:
9
Step-by-step explanation:
Answer:
Step-by-step explanation:
when you multiply a negative times a negative it turns into a positive number
-4.5·2=9
If you did * for exponents then the answer is 20.25
same rule applies, when you multiply a negative times a negative it turns into a positive number
-4.5·-4.5=20.25

Scott is collecting cans for his school's annual food drive. He has already collected 3 cans but wants to collect at least 12 cans in all. Write and solve an inequality to show how many more cans Scott needs to collect to reach his goal.
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that Scott has already collected 3 cans but wants to collect at least 12 cans in all.
The inequality to show the number of cans that Scott needs to collect to reach his goal will be:
x + 3 ≥ 12
x ≥ 12 - 3
x ≥ 9
To each his goal, he has to collect at least 9 more cans.
ABCD is a rectangle.
Rectangle A B C D is shown. All angles are right angles. The length of A D is 5 and the length of D C is 12.
Use the diagram to answer the questions.
The length of AB is
.
The length of BC is
.
The length of AC is
.
Answer:
AB = 12 BC = 5 AC = 13
Step-by-step explanation:
opposite sides of a rectangle are congruent, therefore AB = DC = 12
and BC = AD = 5.
Now, AC is found by using the Pythagorean theorem.
So, [tex]AC^{2}[/tex] = [tex]AB^{2}[/tex] + [tex]BC^{2}[/tex]
= [tex]12^{2}+5^{2}[/tex]
= 144 + 25 = 169
AC = [tex]\sqrt{169}[/tex] = 13
Answer:
12,5, and 13

Three girls reeshma, salma abd mandip are playing a game in a cirvle of radius 5m. Distance from reeshma to salma is 6m, distance between salma and mandip is 6m, find the distance between mandip and reeshma
Answer:
9.6 m
Step-by-step explanation:
Given that :
Radius of circle = 5m
Using the labeled triangle :
Obtain OA:
OA = sqrt(Radius² - AR²)
AR =BM = 6/2 = 3
OA = sqrt(5² - 3²)
OA = Sqrt(25 - 9)
OA = Sqrt(16)
OA = 4
Area of triangle OSM
0.5 * 5 * SM = 0.5 * 4 * 6
2.5 * SM = 12
SM = 12 / 2.5
SM = 4.8
Distance RM = RS + SM
SM = RM
RM = 4.8 + 4.8
RM = 9.6 m

GEOMETRY!!!! pls help (also pls explain)
To answer this question, you need trigonometry.
Are you familiar with the chant soh cah toa?
In here, you can see that the side you have is adjacent to the angle you have, and you're trying to find the opposite side. This means you need tangent = opposite ÷ adjacent
If the angle was 30° 45° or 60° Then there is a table you can use to calculate, but there isn't so just use a calculator
tan 31° = x ÷ 10
when adding and subtracting numbers do you add and subtract the denominator
Answer:
No, you don't.
Step-by-step explanation:
The denominator only changes if you're multiplying/dividing. You may need to create an equivalent fraction to add the fractions together, but you don't add or subtract the denominator.
Hope this helps! Have a great day!
Answer:
No, you adjust the numerator and denominator to a common denominator, then do the addition/subtraction operations with with the numerator, and finally reduce it to the lowest fraction.
Example:
1/3 + 3/4 = ?
change to a common denominator (12 works for 3 and 4)
4/12 + 9/12 = ?
add the 9 and 12
4/12 + 9/12 = 13/12
reduce to lowest form
12/12 = 1 1/12
